About Genetic Diseases
... Genetic diseases are defined as diseases caused by aberrations of genetic material. Therefore, these diseases can potentially be passed from generation to generation. However, not every patient has a family history of a similar problem. This is because new mutations can occur when an individual inhe ...

Mutagen
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
